Knob for Gurdies (a mod of the Nerdy gurdy one) v3

thingiverse

Hi everyone, this is another version of my knob for hurdy gurdy/nerdy gurdy. I made the contact part with the hand palm smaller than the other two I share with you. The reason is that in the hurdy gurdy the knob must roll in the palm. So if the knob is too big, you will not get enough room to achieve that. I printed one in PLA filled with copper (20% metal filled) - renkfore - on a m3d printer without retraction at 60 mm/sec and 250 microns per layer. I was able to put the 2 608 ZZ bearings in it. Alternatively, you can use in-line skating bearings such as ABEC 1 to 7, for example. I now have three knobs that I can test and find the best one that fits my needs.
